DSEV Discovery (Not strictly Star Trek, but heavily Star Trek based!)

My latest pet project. It came about after thinking that, from a structural standpoint, that the designs of Starfleet and most other organizations in the Star Trek universe don't seem totally suited to how space works. For example, I've always found it strange that the nacelles aren't vertically opposed. I also just kind of assumed before I got into it that the saucer spun to provide artificial gravity. So I present this: The Deep Space Exploratory Vessel Discovery.
(Mrs. Sketchup lady standing on the saucer guide track for scale.)

A few notable things:
-The impulse engines are the smaller nacelles, pointing (arbitrarily) port and starboard.
-The Warp Nacelles are the larger ones, the struts pointing dorsal and ventral.
-The disk is the primary work and habitation environment, with artificial gravity provided by spinning when the ship is on a constant trajectory or in orbit.
-The bridge (or "hub") is at the core of the disk, and provides a passage between the disk and the rest of the ship.
-To give some comfort to engineers working at the reactor in the secondary hull, there are several rings throughout the hull that rotate to provide a low level of gravity (when in orbit or a constant trajectory.)

The ship itself is about 630 feet long.

In this alternate reality, I've chosen to knock out artificial gravity and transportation from the repertoire of sci-fi fibs. One still has to keep a form of warp drive to cruise the galaxy, of course, so it's sort of the "One big lie" trope.

Thinking about sketching up what I think some of the interior spaces would look like.

From a visual standpoint, I kind of prefer it to a spoked wheel. I thought, primarily, that the areas closest to the hub would be crew quarters, because sleeping lying down renders the effects of gravity pretty much useless anyway, so the outer ring would be used for workstations and other such things. For visual interest I may poke holes in it at some point, but I just prefer the clean lines of a disk.

For centrifugal artificial gravity, that's about the worst orientation you can use on a spacecraft. It may make it look like a Star Trek style saucer this way, but it's painful to look at from an engineering standpoint.

Thank you for explaining just why you think it's so stupid. I assume that it's because it would be better to treat the neck of the ship like an axle rather than a fork for a spindle. I'd say a reasonable argument for orienting the disk like it is that it decreases the frontal area of the ship, meaning that the ship is less likely to run into debris at speed, and one could say that by being able to place the nacelles closer together would allow for less energy usage in the spacewarp process.

Plus it looks prettier than either a sphere or a front-facing disk/wheel. At least I think so.

It has to do with angular momentum. With the disk oriented the way you have it the ship is going to continually try to turn left (or right depending on the direction of rotation of the disk). If you're going to make it a star trek ship, just go with gravity plating to explain the AG and drop the centrifugal stuff.

Also, think about it, whenever the ship is accelerating, some of the walls are now floors, some of the floors are now ceilings, but which ones depends entirely on where the wheel stopped when you decided to accelerate. If you had it perpendicular to the direction of motion then whenever acceleration occurred then you would have one particular wall become the ceiling and one become the floor, for the entire disk. A much easier condition to plan rooms for.
